# Atypical Presentation of a Cerebellar Abscess Caused by Streptococcus intermedius: Importance of Early Recognition

## TL;DR

A rare case of a cerebellar abscess caused by Streptococcus intermedius highlights the importance of early diagnosis to avoid misdiagnosis as a tumor.

## Contribution

Highlights the atypical presentation of cerebellar abscesses caused by Streptococcus intermedius and emphasizes the need for early recognition.

## Key findings

- Streptococcus intermedius can cause cerebellar abscesses with features resembling neoplastic lesions.
- Early recognition is critical to avoid delayed treatment due to pseudotumoral behavior.
- Combining clinical, radiological, and microbiological data is essential for accurate diagnosis.

## Abstract

A cerebellar abscess due to Streptococcus intermedius is an uncommon clinical entity that may present with features resembling a neoplastic lesion, making early recognition challenging. S. intermedius, a member of the Streptococcus anginosus group, has a marked ability to induce tissue destruction and trigger a pronounced inflammatory response, ultimately leading to the formation of purulent collections with peripheral enhancement on neuroimaging. Although gram-positive cocci are recognized causes of brain abscesses, involvement of the cerebellum by this organism is rare. Awareness of this atypical clinical presentation is critical, since its pseudotumoral behavior may obscure the underlying infectious etiology and delay appropriate therapy. Integrating clinical manifestations, radiological characteristics, and microbiological confirmation is therefore essential for timely diagnosis and favorable clinical outcomes.
